PGIiEON- PROTECTIVE DEVICE.

1 o of New SUN. or New York, in the York, and in the State of how.z'orlz, have ll'tillii l B. ccrtuin new and alhullil linprovo ll) ii:l")isonlrotooti\ .s. and do in; l l"'c'i11't? llu u ll,

cot-ion orm'ioe a shal iu'rchlcntzil taking of poisonoui p lots, and tosuch ends 111; invent on eonsists the )oison protective dorm:hereinafter specified.

In the accompanying drawings--"igures l and 2 are perspective Views ofdiiierent roar being accidentally swallowed, the tab- .cts beingarranged in groups; and

Figs. 3 l fire, .respectivol nwrspective. views snowing sing-do tabletsFigs. fund Accidents frequently occur in whioh'siclrmess or loss of lifeis caused by the taking internally of a poisonous pill or ti blet undersupposition that it ii dilferent and hnrmiess tablet, the kind oftablets thus most frequently taken by mistake being those formed ofbiclilorid of mercury. So far as 1 know, no simple and vs means have 122? been devised which mill prevent such soeidrnts. especially .vlicrethe tublits are when in tho dork. l hore izii uteri n simple means. andone which bellows to be most effective for the purpose of preventingsuch st'cidents.

My invention is capable of embodiment in many (liileren't forms and theillustrated enibodiinent is to be regarded as typical only.

and my invention is not to be confined thereto.

Broadly, my in'venlion consists in attachingz to ihc tablet a device toattract physical attention in ease the tablet or pill is put in themouth or dissolved in 3 glass or" water. l shall will such device 2ilabel. lo the cmhodinienls illustrated in the drawings, such lfibcltakes the form of a thread or string 2 which, in the present instance,is embedded in the tablets l.

in the form of the invontion shown in Fig. 1, the some thread passesthrough a of the form shown in V Patented Mar. 24:, 1914;.

Serial No. 798,384.

number of lfiblfits und I have illustrated the {lll'HHlS as consistin ofhorizontal threads 3 and vertical thread? :2, each tablet having both ithorizontal and vertical thread passing through it. Thu tablets are thusformed into :1 group from which it is impossible lu lulic our nilhrutscrcringtlie threads,

'zmd thus even the slecpiest person would have his attention called tothe fuel lhut tho tubh-i was one of a poisonous nature, assuming thatonly poisonous tablets were put up in this form. \Vhen a tublot isseparuled from the rest of the box it would, as shown in Fig. 2-5, havethe. ends of the threads extending outside of it loosely, and if thetablet were put in the mouth in this form the sense of touch would veryquickly reveal the presence of the three: ls. Even if it be conceivedthat the tublet were entirely dissolved oil the threads, the threadswould reveal thc nature of the tablet which had been dissolved andswallowed, and thus cnable immcdiutr relief to be up'plied.

In the form of my invention shown in Fig. 2, the tablets are simplyconnected by a single thread and the appearance QY-"u dotzu-hed tublotis shown in Fig. 4.

r The threads, being llcxible, would not in the leust interfere with theboxing or bottling of such pills or tablets and their medicinalqualities would not need to be interfered with or impaired in anymimnor, whether the tublcts were bottled or boxed, ronnculul togcther,as shown in Figs. 1 and 2, or dcturhcd, as shown in Figs, 3 and 4.

it is evident lhut any invention will result in tho saving of many livesnow lost through such accidents us those above mentioned.
